Dart heads with FI
Dart heads with FI I was doing some research and im considering the dart heads for my D1SC project. Seems all im finding is people suggesting this head along with a list of others. Or someone saying yes i run the head. But no real review of the actual head, what they like or dislike in the head. Im looking for forced induction specific opinions since the head works much differently when boost comes intgo play. So who has em? Do you like or dislike anything about them? Wish you would have gotten something else? Any tips or tricks with these heads? Anything anyone can tell me would be great cause theres really not much on the FI section about these heads other then people saying its a possible option.
I have used the Dart 225s all year, dont know much about them except I bolted them on and they work. And after a couple head gasket changes they have stayed pretty flat. Swapped springs and seals last week and the valve job still is holding up fine as well as the guides. Put the new springs on and I'll run them another season. On a FI car the size of the port/valves have more impact then then anything so its hard to say how 'good' the ports are compared to anything else. I just wanted a well made brand new casting with no rocker stand or spring pocket issues and these seem to work.
You dont se them a lot on FI cars since the chamber is fairly small, if they made a 72cc version they would be on a lot more FI cars instead of the 6L heads I bet

I have a set of Dart225cc out of the box as well for my 6litre blower motor. I am in the break in process now without the blower on.I feel they should work pretty well though.

Verdad Gallardo -14.9cc is what i got. -8.6 is what i was expecting. I was gonna use a 72cc head for a low 9s compression. Ive decided to use this shortblock though as its done and built buy one of the best shops around (speed inc) and i beleive in it. Im just trying to pick the right head for me, looking for 9.5 or slightly less.
If my math is correct, with stock 6.0 MLS gaskets i will be at X compression with XXCC heads...
62cc = 9.504
63cc= 9.409
64cc= 9.317
65cc= 9.227
66cc= 9.138
67cc= 9.053
68cc= 8.967

I have a set of DART 205s that will be up for sale shortly, they are as cast with 3K on them. I liked them alot but I bought a turbo kit and needed to drop the CR so I bought some heads with a larger combustion cahmber and am rebuilding my shortblock so I dont need them.
